Due to its superior performance characteristics, screw vacuum pump has become a hot star equipment in the semiconductor, microelectronics, pharmaceutical, precision machining and other industries. The screw vacuum pump in our country started relatively slowly, and compared with the foreign level, There is still a big gap, then the production of screw vacuum pump at home and abroad what kind of form? Screw vacuum pump Summary of domestic and foreign production 1, the domestic screw vacuum pump business, from 2004 onwards began to profile and structural performance research. In 2007, when the market for domestic dry screw vacuum pumps was basically occupied by foreign manufacturers, domestic companies invested a lot of money to transfer the products to batch production and received strong support from the state to obtain various provincial-level science and technology awards and funds . LG dry screw vacuum pump higher vacuum limit, lower power consumption, with energy saving, maintenance-free advantages. It is the oil seal / jet / water ring vacuum pump replacement products, major pharmaceutical and chemical companies in the country have been widely used. For different process conditions, the overcurrent components (ie, the rotor and the pump and other parts in contact with the gas) are anti-corrosion coating, including nickel and phosphorus coating and PTFE two. 2, Germany and Japan The company officially launched at the end of 1999, screw-type oil-free vacuum pump is a specially designed for industrial applications (non-semiconductor applications) designed dry pump, it is a new design, is designed to solve industrial Application of the difficult vacuum problems, such as dust, tar and so on. This pump is also a variable pitch rotor, an internal compression process, the pump chamber without bearings and seals, greatly reducing the failure rate, there is no internal valve cavity, which is resistant to dust and tar ability, this pump screw internal hollow cooling , Can reduce the rotor temperature and thermal deformation, long screw life. Although China's economy and technology have made great strides, there is still a certain gap between other countries in the world. This is an embarrassment we need to face. From the above analysis of the domestic and foreign production of screw vacuum pumps, we can find out Our gap. On the screw vacuum pump research and promotion, the Chinese still have a long way to go. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
